Specification of Letters Patent.

Patented Dec. 12, 1916.

Application filed November 11, 1914. Serial No. 871,49d.

To all whom it may concern Be it known that I, BENJAMIN ZIMMER, citizenof the United States, resident of Minneapolis, county of Hennepin, Stateof Minnesota, have invented certain new and useful Improvements inTables, of which the following is a specification.

The object of my invention is to provide a table adapted for use in alibrary or sitting room, and readily convertible into a table suitablefor dining purposes.

A further object is to provide a table that will be neat and ornamentalin appearance and of comparatively inexpensive construction.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification, Figure1 is a plan view, partially in section, with the table top removed, Fig.2 is a longitudinal sectional view through a table embodying myinvention, Fig. 3 is a transverse sectional View taken on the line zvmof Fig. 1, showing the table top in its lowered position, Fig. d is asimilar view, showing the top in its raised position, Fig. 5 is atransverse sectional view taken on the line yy of Fig. 1, showing thetable top-raised and the extended position of the leaves, indicated bydotted lines, Fig. 6 is a similar view, show ing the leaves extended andthe table top lowered into the plane of the leaves to adapt the tablefor dining purposes.

, In the drawing, 2 represents the side rails of the table, having endrails 3 and supporting legs l, the table being of the mission type,though the invention can be applied to any style or design of table.

5 and 6 represent cross bars between the rails 2, arranged in pairs inparallel relation, the bars of each pair being spaced apart and the bars5 having guides 7 thereon for vertically slidable plates 8 upon whichthe table top 9 is supported and held in position thereon by suitablemeans, such as dowel pins 10. The plates 8 are preferably arranged ateach end of the table near the middle line thereof and have a limitedvertical movement through slots 11 provided in the end portions of aplate 12 that extends from end to end of the table along the middlethereof and is secured to the end rails 3 and the cross bars 6 by screws13 or other suitable means. The end portions of the plate 12 areconnected along the middle of the table by acomparatively narrow stripid and leaves 15 have their inner edges seated against the longitudinaledges of the plate 12 and are pivotally connected at 16 to one end ofthe links 17 whose opposite ends are pivotally connected to bars 18which cross one another and are pivoted at 19 to the strip 14, the linksand bars forming a lazy tong construction, for operating the leavessimultaneously, the movement of one leaf in or out causing a similarmovement of the opposite leaf.

Each leaf is provided with bars 20 mounted transversely thereof andslidable in slots 21 in the side rails 2 and in the space be tween thecross bars 5 and 6, the lower edges of these bars having a slidingbearing on the side rails 2 and their upper edges bearing on the undersurface of the plate 12 and being guided by these surfaces in theoutward and inward movement of the leaves. The inner ends of the bars 20are provided with depending pins 22 which, when the leaves are drawnout, engage the side rails 2 of the table and limit the outward movementof the leaves. When the leaves are pushed in to contact with thelongitudinal edges of the plate 12, the outer edges of the leaves willregister with the corresponding edges of the table top as indicated inFig. 3, the table then presenting the appearance of an 0rdinary libraryor sitting room table. When, however, the table top is raised and theleaves are drawn out, the top may be lowered between the leaves,assuming the position indicated in Fig. 6, where the top and the leavesare shown in the same plane, the table being thereby considerablyenlarged and made suitable for use as a dining room table. Thisidea,first raising the table top and then drawing out the leaves untilthe top can be lowered between them,1 regard as an important feature ofmy invention.

For the purpose of raising the table top quickly and conveniently, Iprovide levers 23, pivoted at a point intermediate to their ends on thecross bars 5, as at 24c, and hav ing lugs 2-5 at their inner ends whichfit into sockets 26 in the plates 8. The outer ends of the levers areprovided with lugs 27. Arms 28 are pivoted at one end in the cross bars5 and are connected to one another by suitable means, such as a bail 29,and these arms are provided with lugs 30 which bear on the outer ends ofthe leaves 23 and contact with the lugs 27, so that when the arms arerocked by the outward movement of the bail 29, the levers 23 will betilted to lift the plates 8 and raise the table top. During this outwardmovement of the bail, the lugs 30 will swing past the pivotal centers ofthe arms 28 and thereby the bail and levers will be locked and preventedfrom returning. prematurely to their normal position by the weight ofthe table top or articles which may be placed thereon. When the tabletop has been lifted, the operator, grasping one of the leaves can,through the connection with the opposite leaf, pull both of the leversoutwardly to the position indicated by full lines in Fig. 6. When thishas been done, the table top can be lowered between the leaves byswinging the bail inwardly, thereby allowing the top to drop downbetween the leaves in the same plane thereof, where its upper surfacewill form a continuation of the leaves and provide a table suitable fordining purposes.

This invention may also be applied to a teawagon orlike device, mountedon wheels and capable of movement from place to place. The applicationof the invention to such a construction would be substantially as shownherein, and I have thought that no further illustration of the specificapplication would be necessary.

To assist in raising the table top I prefer to provide springs 31connecting the arms 28 with the side rail 2 and normally under tensionwhen the table top is in its lowered position. These springs can be madeof suitable tension to aid the operator materially in swinging the bailfrom the position shown in Fig. 3 to thatillustrated in Fig. 4c.

The table can be made in various sizes and designs, and in various waysthe details of construction may be modified without departing from thespirit of my invention.

I claim as my invention:

1. A table comprising a frame, a top, vertically movable supportswhereon said top is mounted, levers pivotally connected with saidsupports, a bail pivoted on said frame for operating said levers, andleaves normally under said top and movable outwardly when said top israised, said top,
